# Is electric current a vector?

No, electric current is not a vector quantity. The direction of current is determined by the polarity of a battery. Current in a wire does not change even if the wire is tied or bent. To be a vector, a quantity must obey laws of vector addition. But current does not obey the laws of vector addition.

​In the above figure, current in wire $OC$ is $7A$ (vector sum will be $5A$). Since current does not follow triangle law of vector addition, so it is a scalar quantity.
